Fringe star Anna Torv has admitted that she would love the chance to play the alternate Olivia more.

Speaking to TrekMovie, the actress explained that she enjoyed creating a different version of her character.

"It was fun," she said. "We spent heaps of time trying to work out what you do when it's kind of the same person - all the genetics are exactly the same - it's really just that they've had different lives.

"It was quite interesting to think about personality, and not obsess about making them different but rather just playing actions that you wouldn't normally play."

She added: "I hope I get to do more of it. She was really a blast, to kind of get out of this suit and everything too was fun. But I still love Olivia."
